.To cll whom itfmay concern:

;Be itknown that SAMUEL BRO'NS'I'IEN, a citizen of the United States, residing at St. Paul inthe county of Ramsey and State of Minnesota, has invented certain new and in Nonstretchable of which the following is a specification, reference being bad to the accompanying drawings.

K This invention relates to mattresses and it isjan'object of the invention to provide a novel and improvedmattress constructed in a'ilnanner" whereby the same is non-stretchab e."

Another object of the invention is to provide a novel and improved mattress involving a"meth 'od of shrinking the edges down to agiven size.

The invention consists in the details of construction and in the combination and arrangement'of the several parts of my improved mattress whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

. as will be hereinafter morefully set forth. The novel features of my invention Wlll i accompanying 'drawings,

hereinafter be definitely claimed.

In order that my invention may be the better'understood,-'I will now proceed to describe the same with reference to the wherein:

Figure I is a view in top plan with a portion broken away of a mattress constructed in accordance with my invention.

Figure 2 is a fragmentary view in perspective illustratin a means herein e mbodied for-"tightening the holding strips associated'with the box strips; and

Figure Sisa diagrammatic view illustrat ing the' manner of cutting either the top if or" bottom of the mattress to obtain the a" mattress which side's ofthe -mattress desired shrinkage to assure the maintenance of the completed mattress against stretching. 'A's disclosed in theaccompanying drawings, 1 denotes either the top or' bottom of has associated in amonventional manner with the marginal rti'oii"'thereof, the box strip 2. ecure to the str-ip2 at the sides and ends of the mattress are the flaps F,-thefiaps at the being in opposed relation as is also the case in connection with the flaps carried by the ends of the mattress.

"Each'of 'thefla'ps F comprises a sheet of dimensions and folded ably by lacing cord 5.

i922. semi no. 585,580.

Substantially bridging the space between a pair of opposed flaps F is a strip 6 ofa width substantially the same as the width of the flaps F. The extremities of the strip 6 are provided with the eyelets or 'gromets 7 through which the lacing cord 5 is disposed The lacing 'cords 5 serve to provide effective means to pull the strip 6 taut. The advantage of the co-acting strips 6 and flaps F is to assure the proper building of the mattress. In cutting the top or bottom to a size of four feet eleven inches in width and six feet eleven inches in length n sewin up the mattress approximately one inch is taken up in both width and length, bringing the net size to four feet teninches by sixfeet ten inches. The upholsterer takes in through the center the slack which will bring the size of the .mattress down to a basis of four feet six inches'by' six feet three inches. The flaps each have one and one-half inches free and .as the longitudinal strips 6 and transverse strips 6 are six feet one inch and four feet four inches, respectively, the excess on the flaps F is one and one-half inches on each end of" the strips 6, making'a total length of six feet four inches and four feet seven inches, respectively. The cords 5 serve to take up the excess and resulting in a frame that is eggactly four feet six inches in width and six feet three inches in length. The mattress on this basis cannot possibly stretch. The efiiciency of the cords 5 j is further facilitated in view of the fact that the eyelets or gromets 4 and 7 are positioned onefourth inch inwardly of the adjacent edges of a flap For strip 6. I a To further facilitate the maintenance of the mattress against stretching or distortion I find it of advantage" to end portions of the top or'lbottom of the mattress as is diagrammatically illustrated in Figure 3. The top or bottom 1, after being initially cut'in the desired dimensions, has each corner cut therefrom on the slanted line of'cut a, said lineof cuta being frominitially cut the a point substantially one and one-half inches inwardly ofthe longitudinal edge of the top or bottom and to a point substantially ten inches inwardly of the adjacent end of said top or bottom. I

Each end of the top or bottom at a point substantially two and one-half inches inwardly thereof at its sides is cut on the lines I) to the transverse center of the top or bottom 1 ata point a substantially one and onehalf inches inwardly of the adjacent end edge of said top or bottom 1.

By cutting the end portion of the fabric of the top or bottom 1 on this basis one and one-halfinches of slack is taken up at each end which gives a total of three inches slack taken .up in the width. At the same time two and one-half inches in length is taken 7 up at each end portion or a total of five inches. This computation occurs only at the extreme edges of the top or bottom of themattress .but there is a gradual take up from the longitudinal edges to the transverse center of the top or bottom. The shrinkage at the transverse. center of the top or bottom is 1 inch or one-half inch at each end so therefore the upholsterer need only take up six inches in upholstering.

After the ends of the top or bottom 1 have been cut on the lines a and b as hereinbefore referred to, it is only necessary to round off the corners as at d to make a round cornered mattress.

From the foregoing description it is tho ght to be obvious that a mattress constructed in accordance with my invention is particularly well adapted for use by reason of theconvenience and facility with which it may. be. assembled, and it will also be obtress being vious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself tothe precise arrangement and formation of the several. parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

, 1. A tufted mattress comprising, in combination, a top,-a bottom, a box strip associated with the to and bottom, said top and bottom being initially of a. length in excess ofthe length of the finished mattress, said top and bottom each havingits opposite end portions cut. on lines converging from the sides thereof toward the transverse center,

said converging ends at the sides of the matspaced, apart a distance equal to the finished length of the mattress, the tufting of the mattress drawing in the intermediate parts of the end portions of said top and bottom, and strips connecting the strip, the connections etween said strips and the box strip being spaced apart a distance substantially equal nation, a top, a bottom, a box strip associated with the top and bottom, said top and bottom being initially of a length in excess of the length of the finished mattress, said top and bottom each having its opposite end portions out on lines" converging from the sides thereof toward the transverse center, said converging ends at the, sides ofthe mattress being spaced apart a distance equal to the finished length of the mattress, the tufting of the mattress drawing in the im termediate parts of the end portions of said top and bottom, strips connecting theend portions of the box strip, the connections be. tween said strips and the boxstrip being spaced apart a distance substantiallyequal extremities of said out portions at each end:

of the top and bottom being spaced apart a distance substantially equal .to the width of the finished mattress, and strips connecting the side portions of the box strip, .the connections of each of said. strips with the side portions of tliebox strip being spaced apart a distance substantially equal,v to the width of the finished mattress.

3. A tufted mattress comprising, in combination, a top, a bottom, a box strip .associated with the top and bottom, bottom being initially of a length in excessof the length of the finished mattress, said top and bottom each having its opposite end portions cut on lines converging from the said top and sides thereof towardvthe transverse center,
